    Does RISC-V have security benefits since it is open source? Is it easier to detect hardware backdoors if it is used instead of x86 or ARM?

      RISC-V instruction set (ISA) is open source. But the actual implementation (microarchitecture) has no such obligations. And among the implementations that can run Linux, none (that I know) are open source designs.

      With regards to hardware backdoors - no, closed source RISC-V implementations are not easier than x86 or ARM to audit for security.

      I think the CPU chips themselves are closed source but the architecture is open under MIT so this means anyone can close them

          You would have to get a special version of lwjgl for it to even run on risc, and this thing doesn’t have any dedicated graphics hardware. The one guide I saw had Minecraft running on similarish hardware at 2fps.

              I would say yes, but probably not for a lot of users. Minecraft isn’t inherently threaded, and the individual cpu cores on this aren’t super fast (though pretty decent). Another bottleneck would be the io speed, which I have no clue on. Also, why the hell would you run a server on a new laptop when you can buy one of their other pieces of hardware for cheaper?

    This is the best summary I could come up with:


    Known as the Lichee Console 4A, the laptop features a display size of just 7 inches, 16GB of memory, and an LM4A TH1520 processor.

    Despite its small size, the Lichee Console 4A packs the features and functionality that you’d generally expect from a mainstream x86 laptop in this price range: LPDDR4X memory, 128GB of eMMC storage, and an optional external NGFF SSD.

    Display-wise, the video resolution of the 7-inch display is 1280 x 800 featuring capacitive touch touchscreen support, plus a mini HDMI port for external monitor output.

    There’s also a 2MP front camera that should suffice for basic web calling.

    Additionally, there’s also a microSD slot reader, which can expand the device’s storage on top of what it already has.

    Other miscellaneous specs include a battery capacity of 3000mAh, RedPoint (seemingly a copy of Lenovo’s TrackPoint), a 72-key keyboard, an aluminum outer shell, and a weight of 650 grams.

    Hmmm I wonder if it’s possible to hack together that tiny keyboard together with a Steam Deck…
